Django Homework Help by Real Human Python Experts

Django models and migrations

Field types, ForeignKey, OneToOne, and ManyToMany relationships, model managers, custom QuerySets, makemigrations, migrate, and data migrations for schema changes mid-course.

Django ORM queries

get, filter, exclude, Q objects for OR-style logic, F expressions, annotate/aggregate, select_related/prefetch_related for N+1 fixes, and raw SQL when the rubric calls for it.

Views (FBV and CBV)

Function-based views, class-based views, generic views (ListView, DetailView, CreateView, UpdateView, DeleteView), mixins, and decorators like login_required and permission_required.

Templates and forms

Template inheritance, custom template tags and filters, ModelForm and Form classes, FormSets for multi-record forms, validation, crispy-forms when the rubric expects polished styling.

Django REST Framework

Serializers, ModelSerializer, ViewSets and Routers, authentication (Token, JWT, Session), permissions, throttling, pagination, filtering, and OpenAPI documentation with drf-spectacular.

Authentication and authorization

Built-in User model and the AUTH_USER_MODEL swap, custom User models, permissions, groups, login and logout views, password reset flows, social auth with django-allauth.

Django admin

ModelAdmin customization, list_display, list_filter, search_fields, inlines for related models, custom admin actions, admin template overrides.

Testing and deployment

pytest-django, TestCase, fixtures, factory_boy, Selenium for end-to-end tests, and deployment to Heroku, Railway, Render, or DigitalOcean App Platform with gunicorn, nginx, and Docker.

Advanced Django

Custom middleware, signals, Django Channels for WebSockets, Celery for background tasks, async views, GraphQL with Graphene, and full-text search with Postgres.

ORM N+1 queries

The number-one Django performance bug. We rewrite with select_related for ForeignKey lookups and prefetch_related for reverse relations, and the page load time drops from seconds to milliseconds.

MigrationError after model changes

Conflicting migration heads, missing dependencies, or a schema change Django cannot auto-detect. We squash old migrations, write the data migration where needed, and document the order.

CSRF token failures

Forms or AJAX requests rejected with a 403. We add the csrf_token template tag, configure CSRF_TRUSTED_ORIGINS in production, and wire X-CSRFToken correctly for fetch and axios calls.

500 errors in production but fine locally

Almost always ALLOWED_HOSTS, DEBUG=False without proper static handling, or missing environment variables. We configure settings, set up whitenoise or S3 for static files, and add structured logging.

Authentication that fails silently

Custom User model not registered, password hashing mismatch, session backend misconfigured, or missing login_required on protected views. We trace the auth flow and fix the broken link.

Forms not saving the right data

ModelForm vs Form confusion, save(commit=False) misuse, ForeignKey fields not assigned before save. We rewrite the form handling so the data flow is explicit.

Template TypeError or KeyError

Context variables missing, None values not handled, or wrong filter chaining. We pass context cleanly, add defensive defaults, and use the right template filters.

DRF serializer not validating or returning wrong shape

Override validate methods for cross-field logic, use SerializerMethodField for computed fields, handle nested serializers correctly, and configure depth or explicit nested writes.
